前几天有个客户提了一台联想C340一体机，说是有问题，正在玩游戏的时候自己关机了。然后就开不了机，让给维修。。。。<br>
<a href="http://uu126.cn/wp-content/uploads/2015/05/20150501120636_58462.jpg" alt="联想一体机c340的奇妙故障维修经历" title="联想一体机c340的奇妙故障维修经历" target="_blank"  rel="nofollow" ><img  class="aligncenter size-full wp-image-1763"  class="lazyload" data-src="http://uu126.cn/wp-content/uploads/2015/05/20150501120636_58462.jpg" src="https://cdn.jsdelivr.net/gh/moezx/cdn@3.0.2/img/svg/loader/trans.ajax-spinner-preloader.svg" onerror="imgError(this)"  alt="20150501120636_58462" width="700" height="500" /></a>&lt;br / &gt;</p>

  <img class="aligncenter size-full wp-image-1763" src="http://uu126.cn/wp-content/uploads/2015/05/20150501120636_58462.jpg" alt="20150501120636_58462" width="700" height="500" /></a><br />
</noscript> 我开始以为是很简单的问题，就让她在店里等，结果通电后，屏幕不亮，然后音箱噼里啪啦的响，并且隐隐的有糊味，我果断的关电了，需要拆机，我就给她说让他明天再来拿。 我以前没有研究过这款机器的拆机方式，搞了半天，一个螺丝没找到。全是卡扣，于是小心翼翼的，试了十八般武器（一字螺丝刀，镊子，拆手机壳的撬杆，牙齿。。呃，牙齿用不到。。），将近半个小时才拆开：
<p><a href="http://uu126.cn/wp-content/uploads/2015/05/20150501120830_92599.jpg" alt="联想一体机c340的奇妙故障维修经历" title="联想一体机c340的奇妙故障维修经历" target="_blank"  rel="nofollow" ><img  class="aligncenter size-full wp-image-1764"  class="lazyload" data-src="http://uu126.cn/wp-content/uploads/2015/05/20150501120830_92599.jpg" src="https://cdn.jsdelivr.net/gh/moezx/cdn@3.0.2/img/svg/loader/trans.ajax-spinner-preloader.svg" onerror="imgError(this)"  alt="20150501120830_92599" width="750" height="421" /></a>&lt;br / &gt;</p>

</noscript> 终于见到里面的螺丝了。于是把主板，硬盘全部暴露出来，首先，点亮机器，看下哪边异常，结果主板上没有发现异常，用检测卡测试，代码也不跑，只是显示01，cpu都不带启动的，我去，不是主板cpu都挂掉了把，于是我把光驱，硬盘，内存一个个拆了排除，拆掉光驱，故障依旧，拆掉内存，还是如此。。等我把硬盘拆掉，惊喜发生了。基本配件运转启动，屏幕也显示win8的logo，就是提示找不到硬盘，（当然，硬盘我拆掉了），心想，硬盘坏掉了。。。于是我准备拆下来，替换测试，等 我拆下来。挂到别的电脑上了。发现能正常启动，硬盘是健康的。我再把组合数据线拆下来，仔细看的时候才发现，一头的排线处，烧焦了。有一个小突起，是不是这就是故障问题了？我用万用表测了一下接触点，果然，有一个不通，还有两个短路，额，一头冷汗啊。幸亏没有反复加电测试。

</noscript> 我手里没有这样的组合线，附近的电子市场也没有，于是我跑了好几个地方，终于找到一个，还是商家好不容易翻出来的，等我拿回来后，插上一试。机器正常启动，正常进系统，我心里那个欢喜啊。于是，准备装起来再试。结果问题来了，原装的硬盘是拐角的。这样不耽误扣保护主板的盖板， 我拿到手的是直的，怎么都不行。我有点着急了。看来只能动手DIY了。于是，我拿小刀，慢慢的割去一部分，给手动弄弯了；插到主板上。居然也是ok了。我急不可耐的，装好，开机，一切正常，开机测试了半天，也一直正常。哇哈哈，这个线才十多块，加上我的车油费，也超不过五十块，接下来。我在想到底收多少钱合适。本来想给换块硬盘的。但是诚信还是很重要的。我的店刚开没几个月，在积累客户期。我就很实在的给客人讲了导致故障的原因。收了200块。客户很爽快的就给了。然后还说要给我介绍客户（我在想是不是收少了，毕竟这个拆开好麻烦，故障也不好发现，那个硬盘线烧坏的在底下。）。
<p>不过就这样了，毕竟我们还是靠客户支持的嘛。于是，我把我这个小小的经验分享上来，希望能帮到各位。</p>
